Question
## Trigonometric Identities and Simplification

### Problem Statement:
Perform the subtraction and use the fundamental identities to simplify. There is more than one correct form of the answer. 

\[
\frac{3}{\sec(x) + 1} - \frac{3}{\sec(x) - 1}
\]

### Instructions:
1. Rationalize the denominators if necessary.
2. Use trigonometric identities to simplify to the most basic form.
3. Ensure that all steps are clearly outlined and explained.

By manipulating these expressions while using trigonometric identities such as Pythagorean identities, reciprocal identities, co-function identities, and even-product identities, various correct simplified forms can be obtained. 

For further instructions on each type of identity, refer to the educational resources provided.

### Visual Aids:
There is no graphical representation associated with this problem statement.

#### Common Trigonometric Identities:
- Reciprocal Identity: \( \sec(x) = \frac{1}{\cos(x)} \)
- Pythagorean Identity: \( \sec^2(x) - 1 = \tan^2(x) \)
- Co-Function Identity: \( \sec(x) = \csc(90^\circ - x)\)

By mastering these identities, students can simplify and manipulate complex trigonometric expressions more efficiently.
